How TurboPentest tests for this (white-box)
Use of Unmaintained Third-Party Components is caught by white-box software composition analysis when you connect a GitHub repo: Dep Scanner (SCA) matches your dependency versions against vulnerability databases and flags components with known vulnerabilities and outdated or unmaintained releases as part of the pentest. Build-system compromise and download-integrity issues are best confirmed in a manual IntegSec engagement.
Tools: Dep Scanner
